Profit margins are perhaps the simplest and most widely used financial ratios in corporate finance. A company's profit is calculated at three levels on its income statement, starting with the most basic â gross profit â and building up to the most comprehensive â net profit.
Net profit margin is calculated by subtracting total cost from total sales and then dividing the result by total sales. For example, if a business has $1 million in total sales and its total costs equal $800,000, its net profit margin is $200,000 divided by $1 million or 20 percent.
